1. An inductor comprising:
an annular magnetic core, the magnetic core having an internal surface, an external surface, a first end surface connecting the internal surface and the external surface, and a second end surface connecting the internal surface and the external surface and facing the first end surface; and
a coil wound around the magnetic core, the coil including a first coil piece having a length of one turn and a second coil piece having a length of one turn,
wherein
the first coil piece and the second coil piece surround the internal surface, the first end surface, the external surface, and the second end surface of the magnetic core,
one of the first coil piece and the second coil piece has, at a tip thereof, a joint portion to be joined to the other of the first coil piece and the second coil piece,
the other of the first coil piece and the second coil piece has a joint surface, which is a tip surface of the other of the first coil piece and the second coil piece, to be in contact with the joint portion, and
an end portion of the second coil piece is located perpendicular to an end portion of the first coil piece.
